Core Tip

Core tip: In the classic hepatitis B virus (HBV) hydrodynamic injection (HI) model using C57BL/6 mice, only about 30% of the injected mice carried HBV for more than 12 wk. Here we injected the pAAV-HBV1.2 plasmid into C3H/HeN mice and observed that the hepatitis B surface antigen, hepatitis B e antigen and viral DNA persisted even up to 46 wk in about 90% of the hydrodynamically injected mice. Applying interferon-α or entecavir in this HI model decreased HBV DNA in vivo. Hence, C3H/HeN is a suitable mouse strain for the persistent HBV HI model, which might be useful for chronic hepatitis B research and therapeutic drug development.
